Beit known that I, JONAS NoR'rHnor, a

citizen of the United States, residing atl matic bobbin replenishinglooms to fill up the magazine or hopper with bobbins and to allow a fewspare bobbins to lie on the woven cloth between the fell and the breastbeam where they are convenient for insertion in the magazine when thebobbins become exhausted therefrom. This practice occasionally resultsin a bobbin getting caught between the sand roll and the breast beamframe. Now, it is necessary that a certain amount of space be leftbetween the breast beam andthe sand rollin order to convenience theoperative in smoothing the cloth as it passes on to the sand roll, sothat merely to locate the sand roll close enough to the breast beam sothat no bobbins could get caught in the space would be impracticable.Furthermore, to allow the space between the breast beam and the sandroll to be of sutlicient width to permit bobbins to pass through wouldresult in causing bobbins to fall down through on to the floor.

The object of the present invention is to produce a constructionapplicable alike to new and old looms which will prevent theaccidentalcatching of bobbins between the sand roll and the breast beam,and to this end the invention consists in the improvement in loomshereinafter described and particularly defined in the claims.

In the accompanying drawing illustrating the preferred form of theinvention, Fig. 1 is a plan of the front of a loom with the presentinvention applied thereto; and Fig.

2 is a sectional elevation of the sand roll and breast beam with thepresent invention in place. 'c

The illustrated embodlment of the lnvention is described as follows: Thebreast beam 10 ofthe loom extends from side to H side across the frontof the loom above the sand roll 12, `over which the cloth 14 passes onits way to the wind-up roll. A fell is indicated at 16 beyond which thethreads 18 of the war are shown. Extending across the loom rom selvageto selvage of the woven cloth is a bobbin bar 20. This bobbin bar isriveted to two arms 22 supported on pivots 24 which are received inpivot blocks v26 secured by bolts 28 to the breast beam.

Adjusting screws 30 are screwed through the arms 22, and their ends restupon the top of the breast beam. Set nuts 32 are em loyed to hold theadjusting screws 30 in adjusted position. The adjusting screws 30 permitadjustment ofthe'position ofthe bobbin bar to' correspond to diii'ere'ntpositions of adjustment of the sand roll.

. The arrangement is such that the bobbin bar 2O is -supported close tobut slightly above the surface ofthe cloth passing over the sand roll,so that it does not bear uponnor injure the cloth as it passes by it.The bobbin bar catchesany bobbins which may be on the cloth and preventsthem from get ting caught between the sand roll and the breast beam.

It will be observed that the bobbin bar is ivoted on the breast beam sothat when it 1s desired to lift it to rovide access of the operative tothe cloth 1t may be easil and quickly done, and as easily and quicklyreplaced. This also affords the additional space required to permit thepassage of the warp knots when a new warp is put on the loom. e

This invention, it will be observed, isa plicable not only to new looms,but may `1.
